.Be it known that i[,..G-.HARLE s H; RoLLrNs, ofv Watertown, inzthecounty of Middlesex and State of Massachusetts, have. invented certainnew and useful -Improvements in I Floor Connections ,for Water-Closets,of which thei-following is aspecification.

This invention hasfor its object to provide an improved floor connectionbetween the* water-closet bowl and the soil-pipe Orfilbitdbend whichextends beneath the floor.

In carrying out the invention it has been 1 my object to so constructthe connection that it will be concealed within and below the flange orbase of the closet, so as not to detract from the appearance of thecloset when set.

It has further been my object to provide means whereby one of themetallic members forming a part thereof may be rigidly attached to theporcelain base of the c oset and at the same time so connect the closetwith the soil-pipe as to prevent the possible escape of water.

Referrin to the drawin s, Figure 1 represents in si e elevation a c osetwith my improved fioor connection. Fig. 2 represents an enlarged sectionthrough the bottom portion of the same. Fig. 3 represents a sectionthrough the means for securing the ring to thebase of the closet.

Upon the drawings the closet-bowl is indicated at a and is provided withthe base or floor flange a, adapted to rest upon the floor. Thecloset-bowl is provided with an outlet a surrounding which is an annularrecess a for the reception of an internally-threaded ring or annularmember I). Screwed into the ring or member is a pipe-section c, which isadapted to be connected by any suitable coupling with the lead-bend ofthe soil-pipe. Arranged around the mouth of the outlet a? is a pluralityof sockets (2, each of which converges toward its mouth, so as toprovide undercut walls. In each of these sockets is placed aninternally-threaded nipple e, the exterior of which is transverselycorrugated, as best shown in Figs. 2 and 3. The ni ple itself, however,may be tapering toward its end, if desired. Around each nipple is pouredmelted lead to completely fill each of the sockets d, and therebysecurely lock .each of the nipples against removal. These lead plugs byreason of the formation of the tai, pering sockets d effectively prevent1 the-dis location of :the nipples...

The ring :member I; isprovidedtwithapeb tures d,-through-:which screwsf..- 1nayibe passed: into threaded engagement with .the nipples 6, so asto draw=-the said.=member tightly against the top-wall .qfithe socket aThering member 1) 1s bedded-in'Ponfland cement, graftingewax, or othersuitable ace.-

ment, as at h, sothat when the screws fare driven homeawater-tightandiairetight[joint is formed-between the ring andthebowlfl 1It is evident that, if desired, I may omit the nipples e and screw thefastenings f directly into the lead plugs i. The ring member onlypartially fills the recess, and the remainder of the recess iscompletely filled. with parafiin or similar substance.

The invention as thus described provides for a positive connectionbetween the soilpipe and the closet and for the concealment of theconnection within the closet-base. The formation of the recess a in thebase of the closet permits the connection of the ring I) to thecloset-base by the screws f without the heads of the screws projectingbelow the undensurface of. the closet-base to interfere with the propersetting thereof and with the screwsconcealed 'below the surface of saidbase.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, although without attempting to setforth all of the forms in which it may be made or all of the modesof'its use, I declare that what I claim is- 1. The combination with awater-closet bowl having an outlet, and an imperforate base with arecess around the said outlet and with a plurality of sockets convergingtoward their mouths, of metallic plugs in the said sockets, a ringmember arranged beneath the plugs in the said recess, a pipe-sectionconnected to the said ring member andarranged to'register with the saidoutlet, and fastening devices passed through said ring member into thesaid metallic plugs, said fastening devices being located above theunder surface of and beingconcealed by the said closet-base.

2. The combination with a water-closet having an outlet and animperforate base with an upwardly-extending recess encircling the outletand with a plurality of undercut ICC in undercut sockets in thecloset-base, and

fastening members passed upward through the said ring member into thesaid plugs.

4. The combination with a water-closet having an imperforate base withundercut sockets surrounding the outlet, of a ring member,interiorly-threaded nipples externally corrugated and located entirelywithin said sockets, a metallic filling for locking the said nipples inthe said sockets, and screws passed through the said ringifintoitlie'tsaid nipples for rigidly connecting the said ring to the base of thesaid closet, substantially as described.

5. The combination with a water-closet havinglanimperforate base with arecess and with undercut sockets around the outlet, of a ring memberplaced in said recess, internal lythreaded devices in said undercutsockets, and screws passed upward through said ring member into saiddevices for securing said ring member to said closet-base, said screwsand internally-threaded devices being concealed below the upper surfaceof the closetbase and being located above the bottom plane of saidcloset-base.

In testimony whereof I have afiixed my 40 signature in presence of twowitnesses.

CHARLES H. ROLLINS.
